Detection of the nearest Jupiter analogue in radial velocity and astrometry data [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The presence of Jupiter is crucial to the architecture of the Solar system and models underline this to be a generic feature of planetary systems. We find the detection of the difference between the position and motion recorded by the contemporary ...

Turbulence characterization from a forward-looking nacelle lidar [PDF]
Wind Energy Science, 2017 We present two methods to characterize turbulence in the turbine inflow using radial velocity measurements from nacelle-mounted lidars. The first uses a model of the three-dimensional spectral velocity tensor combined with a model of the spatial ...

The BEBOP radial-velocity survey for circumbinary planets [PDF]
Astronomy & Astrophysics, 2019 We introduce the BEBOP radial velocity survey for circumbinary planets. We initiated this survey using the CORALIE spectrograph on the Swiss Euler Telescope at La Silla, Chile.

Spectrum radial velocity analyser (SERVAL). High-precision radial velocities and two alternative spectral indicators [PDF]
, 2017 Context: The CARMENES survey is a high-precision radial velocity (RV) programme that aims to detect Earth-like planets orbiting low-mass stars. Aims: We develop least-squares fitting algorithms to derive the RVs and additional spectral diagnostics ...

Confirmation of the radial velocity super-Earth K2-18c with HARPS and CARMENES [PDF]
Astronomy & Astrophysics, 2018 In an earlier campaign to characterize the mass of the transiting temperate super-Earth K2-18b with HARPS, a second, non-transiting planet was posited to exist in the system at ~9 days.

Radial velocity observations of VB10
EPJ Web of Conferences, 2011 VB 10 is the smallest star known to harbor a planet according to the recent astrometric study of Pravdo & Shaklan [1]. Here we present near-infrared (J-band) radial velocity of VB 10 performed from high resolution (R~20,000) spectroscopy (NIRSPEC/KECK II)

Quantifying the Bayesian Evidence for a Planet in Radial Velocity Data [PDF]
Astronomical Journal, 2018 We present results from a data challenge posed to the radial velocity (RV) community: namely, to quantify the Bayesian “evidence” for n = {0, 1, 2, 3} planets in a set of synthetically generated RV data sets containing a range of planet signals ...
